      @kvicksson the rules are text needs quotes (’ or " matching)
      numbers and true/false should NOT have quotes… as they become strings and not numeric or logical values

      if variable == true will fail with quoted values…

        well with the config:check he would not have found the error, would he?

        In this case perhaps not, but it cannot hurt to run it in order to exclude error(s) before and after this part of the config.
        Normally a 'true' versus true would not cause a black screen, but I might be wrong.
        And a trouble shooting guide would have to start with the config:checkIMHO.

          u don’t know how the module code might fail…
          which is what causes the blackscreen to begin with

              seems odd that there would be two invocations of these modules…

              but as a test, in MagicMirror/config/config.js add

                  disabled: true, 
              

              to both those modules, and restart mm and see what happens

                    I have only one mmm-weatherchart module present.
                    When disabled everything is fine.
                    However, I forgot to remove the single quotes, as I just copy/pasted the config from the thread.
                    Corrected it, but now I get even stronger things.

                    0|mm  | WARNING! Could not load config file. Starting with default configuration. Error found: Error: Cannot find module 'del'
                    

                    I do not have any string with ‘del’ in my config :worried_face:

                          The module is running now, but I get this error:

                          0|mm  | Downloading weather map with signal: FETCH_MAP From URL: www.yr.no/place/Germany/Bavaria/Nuremberg/meteogram.png

                          Then I read somewhere there is a clone of this module that is more recent, so I tried that:

                          https://github.com/szech/mmm-weatherchart
                          

                          Same result: module runs but no file in the cache dir.
                          When opening the URL in the browser, it does show the picture that I do not see on my screen.

                          Oh boy/girl, thought it was a simple syntax thingy in config.js …

                              Correct.

                              I have a few questions.

                              In the original module there is no package.json file, where in the cloned one there is.
                              So, when using the original module, you should NOT use npm install, right ?
                              First of all it will no do anything useful, but it WILL delete your /home/pi/MagicMirror/modules/node_modules/node_helperdirectory and its index.js file.
                              When using the cloned module, you should run npm installin order to install the dependencies mentioned in it, right ?
                              No harm is done to the node_helper dir.

                              Or is it all BS I am telling here (and made the wrong observations) ??

                                    When I use

                                    then it works.

                                    When corrected and doing npm install in the mmm-weatherchart directory, it works

                                        @sdetweil Thanks! This worked for me as it doesn’t kill it anymore. Hope for a quick fix. Can I follow the process somewhere?

                                          Hi @kvicksson ,

                                          To me it seems there are 3 problems here.
                                          You could have a look what the pm2 log says:

                                          $ pm2 logs --lines 100
                                          

                                          You will either have:

                                          Error: Cannot find module 'del'
                                          

                                          or:

                                          Error: ENOENT: no such file or directory, open '/home/pi/MagicMirror/modules/mmm-weatherchart/cache/map-1567097174409.
                                          

                                          or something completely different.

                                          The 3 problems and potential solutions:

                                          You’re config.js entries:

                                          updateInterval: '3600000',
                                          hideBorder: 'true'
                                          

                                          should be:

                                          updateInterval: 3600000,
                                          hideBorder: true
                                          

                                          even if the module could potentially handle it.

                                          If your mmm-weatherchart instal has this file present:

                                          /home/pi/MagicMirror/modules/mmm-weatherchart/package.json
                                          

                                          then you should run:

                                          $ cd /home/pi/MagicMirror/modules/mmm-weatherchart/
                                          $ npm install
                                          

                                          If your mmm-weatherchart instal has this file NOT present:

                                          /home/pi/MagicMirror/modules/mmm-weatherchart/package.json
                                          

                                          then you should NOT run npm instal, has it will cause havoc to you MagicMirror install.
                                          I would do this in this situation:

                                          $ cd /home/pi/MagicMirror/modules/
                                          $ mv mmm-weatherchart mmm-weatherchart.saved
                                          $ git clone https://github.com/szech/mmm-weatherchart.git
                                          $ cd /home/pi/MagicMirror/modules/mmm-weatherchart
                                          $ npm install
                                          
                                          $ pm2 restart pm2
                                          $ pm2 logs --lines 100
                                          

                                          When it works:

                                          $ cd /home/pi/MagicMirror/modules/
                                          $ rm -rf mmm-weatherchart.saved
                                          

                                          Good luck !!

                                            this is all volunteer… you could post an issue to the module owners github repo… maybe he or someone else will respond… I am like you, just another user…
